Реферат: 1285485 Radio navigation NORTH AMERICAN ROCKWELL CORP 2 June 1970 [25 Sept 1969] 26639/70 Heading H4D The invention relates to a circuit for dividing "Loran C" pulses into slower data samples, and utilizes a multi-stage pulse divider for dividing down a high-speed clock pulse signal having a frequency higher than the Loran radio frequency to slower-speed clock pulses for controlling the processing of data samples taken from two phase-related (e.g. master and slave) Loran signals; a multi-stage register holds a number indicating the precise instant in relation to a reference instant established by the slowerspeed clock pulses at which each sample is to be taken, a plurality of chains of sample storage devices transfer samples from the Loran signals to outputs whereat the data samples appear and gating logic controls the gating of samples from storage device to storage device in each chain, the gating logic being controlled by the number in the register in such a manner that the delay experienced by each sample appearing at one of the aforesaid outputs in traversing the corresponding storage device chain is that delay which corresponds to taking the sample at the corresponding one of the instants determined by the number in the register. Means responsive to the data samples changes the number in the register to such a magnitude that the data samples taken from the next Loran cycle tend toward a predetermined relationship between the samples corresponding to coincidence of one of the samples with a predetermined point in one R.F. cycle of one of the Loran signals. As described the pulse divider and the register are binary devices and each sample storage device is a bi-stable for holding a one-bit sample.
